Design

German Type VIIC submarines were preceded by the shorter Type VIIB submarines. U-263 had a displacement of 769 tonnes (757 long tons) when at the surface and 871 tonnes (857 long tons) while submerged. She had a total length of 67.10 m (220 ft 2 in), a pressure hull length of 50.50 m (165 ft 8 in), a beam of 6.20 m (20 ft 4 in), a height of 9.60 m (31 ft 6 in), and a draught of 4.74 m (15 ft 7 in). The submarine was powered by two Germaniawerft F46 four-stroke, six-cylinder supercharged diesel engines producing a total of 2,800 to 3,200 metric horsepower (2,060 to 2,350 kW; 2,760 to 3,160 shp) for use while surfaced, two AEG GU 460/8–27 double-acting electric motors producing a total of 750 metric horsepower (550 kW; 740 shp) for use while submerged. She had two shafts and two 1.23 m (4 ft) propellers. The boat was capable of operating at depths of up to 230 metres (750 ft).

The submarine had a maximum surface speed of 17.7 knots (32.8 km/h; 20.4 mph) and a maximum submerged speed of 7.6 knots (14.1 km/h; 8.7 mph). When submerged, the boat could operate for 80 nautical miles (150 km; 92 mi) at 4 knots (7.4 km/h; 4.6 mph); when surfaced, she could travel 8,500 nautical miles (15,700 km; 9,800 mi) at 10 knots (19 km/h; 12 mph). U-263 was fitted with five 53.3 cm (21 in) torpedo tubes (four fitted at the bow and one at the stern), fourteen torpedoes, one 8.8 cm (3.46 in) SK C/35 naval gun, 220 rounds, and two twin 2 cm (0.79 in) C/30 anti-aircraft guns. The boat had a complement of between forty-four and sixty.

Service history

After training with the 8th U-boat Flotilla, the boat became operational on 1 November 1942 when she was transferred to the 1st flotilla.

First patrol

U-263's first patrol began when she departed Kiel on 27 October 1942. She entered the Atlantic Ocean after negotiating the gap between Iceland and the Faroe Islands. There followed a series of attacks west of Gibraltar, first by the U-boat on two freighters, then on the submarine by surface ships (on 20 November), aircraft (on 24 November) and a submarine (on 26 November), all of which she was lucky to survive. Even so, the damage sustained needed 13 months of repairs. She arrived at La Pallice / La Rochelle in occupied France on 29 November.

Second patrol and loss

The boat departed La Pallice on 19 January 1944. She was sunk the next day in the Bay of Biscay during a deep dive trial.

Fifty-one men died; there were no survivors.
